I don't think that there would be a problem with 5 - 10 at all. I'd rather have those numbers myself. If you're not concerned about wanting M/F pairs, going for males only will keep things settled down more. The spawning motive is what causes all h**l to break loose. Also make sure your tank has lots of refuges and "sight-line breakers" such as tall pieces of driftwood and lots of plastic plants. This will discourage continuing pursuit. I find that Vieja and Paratheraps are generally less aggressive than other "roughhouse" genera such as Nandopsis, Caquetaia and Parachromis. Good luck with your project.
